25 attached to the front portion of the sides thereof at their lower ends, and at their upper ends, to a windlass drum 26 secured on the windlass shaft 27 mounted in suitable bearings on the upper ends of the pedestals ward.

10. Here it may be noted that these windlass drums Q6 are tapered and have spiral channels so arranged that the greatest force will be exerted ,through the cables in effecting the initial lift of the scoop.` An accelerated winding speed will be produced as the scoop is raised. This causes the cable lifting device to do its hardest work slowly andA then to make up lfor lost time by increasing its speed after its hardest work has been done. i

. Obviously, when the front end 'of .the scoop is first raised, into the position shown by full lines in Fig. 1, little or no horizontal travel will be given to the rearend of the scoop, so that the open rear end of the said scoop will remain close to the rear end plate 14E until after the front end of the scoop has been raised far enough to throw the bottom of the scoop into an approximately level position and clear above the surface of the ground. When the scoop is raised into such position, its open front end is brought just in the rear of an upright front end vplate 28 which is fixed to the side barsof the truck frame 11, and extends completely across in front of the scoop. When the scoop is thus raised into an approximately horizontal position, lor even into a position inclining slightly backward, its rear end will be closed by the rear end plate 14C, and its front end will be nearly or quite closed .by the front V`end plate 28, so that the scoop then affords a very serviceable carrying receptacle.

When the front end of the scoop is further raised, the extreme front edge of its bottom plate will move nearly on a vertical line until after it has passed above the upper edge of the front end plate Q8, but thereafter it willbe projected slightly forfront end of the scoop, the rear rollers 23 will travel in the side bars of the frame 11 and the rear end of the scoop will move forward and away from the rear end plateA 111, thus causing or adapting the scoop to dump its load from the rear end.

For some purposes, it is desirable that the scoop have aI removable or displaceable gate at its rear end. Such a gate 29 as shown l has mounted guidefways ,30 formed on the inner surface of the rear ends of dthe sides of the said scoo 21. l

Obviously, w en the gate 29f is in place, and the scoop is inclined backward by raising of the front end thereof, the load will Under releasing movement of the windlass shaft 27 will be driven from one l of the truck wheels thereof. These connections are preferably as follows:

Secured to the hub of one of the large wheels 6 is a large sprocket wheel 31that is alined with a smaller sprocket V32 that is secured to the common sleeve-like hub of a pair of reversely facing beveled gears 33 mounted to rotate freely and slide laterally on a spindle 34 rigidly secured to the upward end portions of the adjacent pedestal bars 10 and 10a. The beveled gears 33 are adapted to be engaged, one at a time, but at will with a beveled pinion 35 that is securedto a short horizontal shaft 36 mounted in a bearingbracket 37 on the upper ends of the adjacent pcdestal bar 10*L and brace bar 13. A. worm 38 is secured on the shaft 36 and meshes with a worm gear ,39 that is secured to one projecting end of the windlass shaft 27. At one end, the worm shaft 36 has a projecting annular shank' with which a crank 4R0, indicated by dotted lines in Fig. 1, is adapted to be applied, for use, when it is desired to raise or lower the front end of the scoop by hand power.

`When both gears 33 are disengaged from the pinion 35, the worm and gear will lock the scoop in any adjustment in which it may be set, and may then, if desired, be moved by operation of the crank 40.

rlhe common hub of the gears 33 and sprocketl 32 has a grooved channel that is lever 41 that is pivoted to a suitable support on the bracket 37. The extended arm of this bell-crank shipper lever 41 stands in such position that it will be 'engaged and caused to move the two gears 33 into neutral or released positions whenever the front end of the scoop is raised to its extreme limit shown by dotted lines in Fig. 1. Such engagement of the bell crank 41 by the adjacent side plate of the scoop will move the gears 33 from left toward the right, in respect to Fig. 3, and hence, will disengage the right hand gear 3; from the pinion 35and instantly stop the winding action of the windlass.

the. pinion 35 and the lowering movement of the scoop will beproduced by engaging the 'l 10 engaged' by one end of a bell crank shipper not be dumped until the gate 29 has been left hand gear 33 with said pinion. A draw 130 which it is forwardly inclined for taking scoop is rearwardly vinclined to discharge up load to another position into which it l its load. 10 is rearwardly inclined for dumping the In testimony whereof I aix my signature loadgthe -said truck frame having a rear in presence of two witnesses.
